Magnetic Perturbation of the Lowest Triplet States of Aromatic Molecules by Dissolved Oxygen

THE absorption spectrum of benzene in the region 2795–3650 A. has been measured by Miss Pitts1. She observed a shoulder at approximately 2900 A. which has been tentatively assigned by Pariser2 as a transition to a 3E1u state. Since it had been shown that oxygen dissolved in benzene absorbs strongly in this region3, the spectrum has been re-investigated… CONTINUE READING
